Gas filter is the special product supporting the use of gas turbine flow meter produced by my
company, it also conforms to the requirements of the flow meter. According to the statistics,
installing gas filter can effectively avoid the damage of flow meter caused by the impact of
impurities. It can reduce more than 90% failure rate of the instrument, and it is one of the necessary
equipment of gas metering scene.
Gas filter can also be applied to all kinds of pressure regulating devices, it is an important
device to filter dust and impurities in the gas such as dirt and make sure normal operation of all
kinds of gas equipment.
When the gas flows into the meter, it first moves through the front diffuser and accelerates.
Since the turbine blade is different from the direction of flow; it thus creates rotating moment and
starts to spin after overcoming the resisting moment and friction moment. When all these moments
come to balance, the rotate speed of the turbine becomes stable and there appears a linear
relationship between the flow and the turbine.
Meanwhile, the magnet on the rotary transmitting plate changes the magnetic resistance of the
sensor regularly and both ends of the sensor thus senses the pulse signal which is in direct
proportion to the volume flow rate of the gas. After being amplified and reshaped by the praevia
amplifier, the above signal, together with the signals of pressure and temperature detected by
corresponding sensors, is sent to the flow totalizer for processing. Eventually, the normal and
volume flow would appear on the screen.
